Sample groups used in this research were executives employees and service receivers of the hotel. Samplesize was 400 persons from purposive sampling and accidental sampling. Instruments used in this research were questionnaires. The data were statistically analyzed in terms of frequency percentage mean standard deviation and analysis of variance (ANOVA). The study result found that most of the sample group were female ages from 31-40 years occupations were government officers having monthly income of 10001-15000 bahts. Most samples had Bachelor’s Degree or equivalent; their relation with Suan Dusit Place Hotel were consumers of the food service operation mostly using service of the food service in the type of buffet. The purpose of the food service was to hold meeting or seminar. They knew about the hotel service providing of food service by informing from one person to another. The opinions of manager employees and food service receivers regarding guidelines of development of banquet of Suan Dusit Place Hotel Suan Dusit Rajabhat University in the overview it was found that service of employees food and form of food service should be developed at a low level.

The objectives of this study were to dry Chaploo Leaves at 3 levels: 50 60 and 70C for 3 hours. It was found difference in the moisture values aw and color significantly (p<0.05). 60C is the best value. Then based on 3 formulas of Cereal Bar mixed with Chaploo leaves sensory evaluation in terms of color flavor taste texture and overall acceptable were conducted. Scores of nine levels (9-Point Hedonic Scale) was used for taste test. Factorials Randomized complete Block Design (RCBD) compared the differences of the measures Duncans New Multi Rank Test (DMRT) found that the scores for flavor taste texture and overall 3

A study on the motivation to participate in student development activities of the RMUTPs students was done with the objective to verify the level of the internal motivation (human relationship social service self - study for development and carrier path ) anf external motivations (location comfortable of travel a period of activites the content of activitiesinstructor and profit) and compare the differences of motivation rating scale base on personal factors : sexuallevel of studentfaculty GPA (grade point average) experience in participation and the information receiving. The study sample of 450 students was randomly selected from RMUTP. undergraduate students from 9 faculties.The data were collected by questionnaire (5 rating scales) and will be evaluated in frequency mean and standard deviation. T-test and one-way Anova used for comparing means at

The development of dried water chestnuts is aimed to study the appropriate concentration of calcium chloride for preparation of water chestnuts before drying process; a proper duration for drying process by using hot air oven; the comparison of drying processes between solar dried-oven and hot air oven; and the use of dried water chestnuts for Thai dessert products. The research result can be summarized that the concentration of calcium chloride solution is 0.25% that yield the best quality for water chestnuts which had 0.63 water activity (aw); 3.47 moisture content color value of (L*) 62.38 (a*) 4.82 (b*) 35.66; and 0.79 specific density. It also yields the best quality to rehydrate water chestnuts comparing to their previous condition. A proper drying duration of water chestnuts soaking in 0.25% calcium chloride by using solar dried-oven at different duration of drying. Dried water chestnuts dried at 9 hours and average dehydration temperature 50-55 Celsius had 0.31 water activity (aw); and color value of dried water chestnuts is of bright red with (L*) 80.14. Also the brightness of rehydrated water chestnuts decreased to (L*) 58.30 and firmness (Newton) to 68.70. By using hot air oven the study of a proper duration of soaking water chestnuts in 0.25% calcium chloride indicated that drying for 3.5 hours of drying time water chestnuts had highest moisture content while drying for 4.5 hours had the least moisture content. Therefore decreasing of moisture content depends on the drying duration with different methods. The study also found that dried water chestnuts using solar dried-oven had less water activity (aw) and moisture content than those using hot air oven. Moreover dried water chestnuts from solar dried-oven had brightness value (L*) less than those from hot air oven; but dried water chestnuts from solar dried-oven had more reddish yellow than those from hot air oven. Also there is similarity of specific density of water chestnuts from both drying methods. For rehydration of water chestnuts color values of these 2 methods are similar. However color which is similar to fresh water chestnuts is resulted by drying water chestnuts with hot air oven; and the brightness (L*) of water chestnuts texture increases. Also value of (a*) and (b*) of water chestnuts from hot air oven are more reddish yellow. Meanwhile firmness (Newton) from drying with hot air oven is able to maintain strength or firmness of water chestnuts. Percentages of water chestnuts absorption are similar between two drying methods. The sensory test of Thai pudding using dried water chestnuts indicated that there is no statistically significant at 95% level of average scores in the terms of color smell taste dried texture and overall acceptance. The result of microbial analysis from dried water chestnuts found that there is no microorganism. In addition the result of raw material cost calculation showed that drying 1 kilogram of fresh water chestnuts yielded 108 grams of dried water chestnuts. The total cost of production is 48.43 Baht per kilogram.
